Dimensions Width 12.2 inches – Height 19.4 inches – Depth 4.7 inches BEFORE INSTALLATION Before installation, contact your local gas dealer or gas management department, directly or indirectly, for a qualified engineer’s opinion, because improper installation is dangerous to safety, or may even endanger your life.
Installation requirements Do not install the water heater in a bedroom, basement, bathroom, or any room with poor ventilation.
Installation Installation mounting Mount the water heater vertically on the upper bolt without any inclination and tighten lower holes with expansion bolts. Piping, plumbing, and exhaust venting LPG users are required to use a standard regulator that will supply 44,000 BTU at a pressure of 11” WC. Gas Inlet (1) For LPG users, connect the gas inlet and the gas pressure-regulator to the gas cylinder. (2) For NG users, contact the gas dealer to connect with a suitable pipe.
4. Battery Cell Installation Do not confuse the positive and negative ends of the D cells. (Fig.8) 5. Flue Installation As this water heater is flue type, the waste gas exhaust pipe must be installed. (Unless you are using this heater outdoors in the open) (Fig. 9) Basic requirements: The inner diameter of the flue: ∮90mm. (3.54 inches) The main body of the flue must be made of stainless steel material.
Operation 1. Preparation before Ignition Make sure the type of gas used complies with that stipulated on the label of this heater. If mounted inside a building or structure, comply with combustion air requirements. (See below.) Turn on the gas valve. Turn on the water valve, faucet or tap (making sure there is water flowing out), there will be a "clicking" ignition sound. The burner will ignite and hot water flows out almost instantly.
cause an accident. ■ Accidental Fire Prevention Make sure that the flame of the heater has extinguished before leaving the room or going to sleep. Turn off the main gas valve and the water valve in case of water leakage. Do not pile inflammables, explosives or volatile materials anywhere near the heater. (Fig.13) Do not place inflammables like towels or clothing onto the waste gas exhaust outlet or the air inlet. (Fig.
■ Carbon Monoxide Poisoning Prevention Excessively high winds may cause the exhaust to back-flow. During high wind conditions, please stop using the heater or it may lead to a dangerous situation. In confined spaces the burning of gas consumes large amounts of air and produces gases which contain certain amounts of carbon monoxide. Thus, the heater must be fixed in a ventilated location.
■ Preventing Overheating - Scalding ● ● After shower, or when the water temperature control is still at “high” position, be careful of the temperature of the water at the beginning and ending of shower, as it may remain high and scald your skin. During or right after use, do not touch any part of the heater other than the control knobs, especially the parts around the flame indicator window and exhaust components. These parts are hot.
Combustion air requirements Appliances located in unconfined spaces: a) An unconfined space is one whose volume is greater than 50 cubic feet per 1000 Btu per hour of the combined rating of all appliances installed in the space. b) Installations in structures that have been tightly constructed (air infiltration rate of 0.40 ACH or less) must be provided for combustion air per the National Fuel Gas Code. Consult a HVAC specialist if your air infiltration rate is questionable.
